Here are 2 frames of my noisy video: http://www.europephoto.com/info/montage_video/frame.jpg http://www.europephoto.com/info/montage_video/frame2.jpg As I can't get any good result with denoising the picture, I choose to use the highest bitrate possible... The camcorder is an old Hi8 model. Now,

2006-04-07 Thread Nicolas
Steven, I just used mplex on a video encoded at 9000kbps, and guess what... no error. You were right! =) I'll now try different bitrate value in order to find the highest usable one. Thank you very much! Nicolas. --- This SF.Net email is spons

Just in case someone might ask/wonder... I did not try to explain, why we have (601) 720x576 or 720x480 pixels per frame (which mainly is related to 2,25 MHz and some factor of six...) .. I just wanted to derive the resolution a HI8-camcorder can have. cu Stefan -- Gnomemeeting/Netmeeting: callt
